We visit the largest geothermal operation in the world to see how heat from the earth's core is transformed into electricity. We meet a chemist, geologist, plant operator, environmental manager and engineer as they show us how they manage steam production wells and electric generators. This growing field relies not just on professionals with advanced degrees but entry- level workers who drill the wells and maintain the power plants in this vanguard of clean energy. Jobs profiled in this program include:Geologist, Project Manager, Chemist, Environmental Manager, Plant Operator.
